Nor145 Sound Level Meter

The Nor145 is a Class 1 sound level meter engineered for professionals who demand laboratory-grade accuracy in the field. Fully compliant with IEC 61672-1 and IEC 61260-1, with type approvals from PTB and LNE, the Nor145 delivers legally defensible noise measurements for environmental monitoring, occupational health assessments, and building acoustics testing across the GCC region and beyond. Designed with a large 4.3-inch color touchscreen and an intuitive smartphone-like interface, the Nor145 minimizes training time while maximizing productivity. Simultaneous A, C, and Z frequency weighting combined with real-time 1/1 and 1/3 octave spectrum analysis gives engineers the data resolution needed for Saudi General Authority of Meteorology and Environmental Protection (PME) compliance reporting, UAE municipality noise ordinance enforcement, and construction permit noise monitoring under Vision 2030 mega-projects. Built-in 4G LTE and WLAN connectivity set the Nor145 apart from conventional sound level meters. Engineers can remotely access live measurements, configure alarm thresholds, and retrieve historical data from any location through the integrated web server or NorCloud platform. This capability is essential for large-scale infrastructure projects such as NEOM, the Red Sea Project, and Dubai Expo legacy developments where multiple monitoring points must be supervised simultaneously. The integrated GPS/GNSS receiver automatically geo-tags every measurement, producing audit-ready documentation for regulatory submissions. Voice and text annotations can be attached directly to measurement files, eliminating the need for separate field notebooks. With over 120 dB single-range dynamic range, the Nor145 captures the full range of environmental and industrial noise without manual range switching, from quiet residential areas at 25 dB(A) to construction sites at 140 dB(A). Whether deployed for airport noise monitoring under ICAO guidelines, occupational noise exposure assessment per ISO 9612, or community noise complaint investigations, the Nor145 provides the precision, connectivity, and durability that acoustics professionals across Saudi Arabia, the UAE, Qatar, and the wider Middle East require for regulatory compliance and environmental stewardship.
